SPECIFICATION forming part of Letters Patent No. 550,482, dated November 26, 1895.

Application filed May 20,1893. Serial No. 474,989. (No model.) Patented in England December 5, 1892, No- 22,207.

To CLZZ whom it may concern.-

l3e it known that we, LAsCELLEs CARR and GEoRoE SoUTHEY, subjects of the Queen of the United Kingdom of Great Britain and Ireland, residing at Cardiff, in the county of Glamorgan, England, have invented certain new and useful Improvements in. Rotary Nu mberingliachines, (for which we have obtained a patent in Great Britain, No. 22,207, dated December 5, 1892 and we do hereby declare that the following is a full, clear, and exact description of the invention, reference being made to the accompanying drawings, which are to be taken as part of this specification and read therewith, and one which will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in the mechanism and devices for, first, rotating the printing-disks continuously and for making the units-disk present a fresh type after each impression; second, preventing the impression being slurred; third, advancing the printing-disks to the paper before the impression is made and for withdrawing them afterward, and, fourth, making the tens and higher value disks present a fresh type after each impression.

The accompanying drawings are to be taken as part of this specification and read therewith. They illustrate the construction and use of the invention for and with a printingmachine of the rotary type, for which type it is specially adapted.

a a are parts of the side frames of arotary printing-machine; b, the type-cylinder; I), its shaft; 0, the blanketcy1inder; 0, its shaft, and cl, the principal and first-motion shaft of the n umberin g-machine. This last-mentioned shaft is supported in bearings d, which are adjustable vertically in either direction in standards (1 by means of set-screws (Z (1 working through cross-pieces d (Z The standards (Z d are bolted upon the side frames a a, respectively, in a proper position for supporting the shaft d parallel with the shafts Z) c and with its axis in. the same vertical plane as that of the shaft 0 of the blanket cylinder 0. Suitable provision is made for driving the shaft (Z from any convenientlysituated revolving part of the printing-machine. The details of the mechanism for so driving the shaft (Z may be of any suitable kind. The mechanism illustrated in Fig. 2 consists of a gear-wheel 6 fast on the end of the shaft 0 and meshing with a second one 6 fast on the end of the shaft (1. The ratio between these two gears is shown as three to one, but this may be varied.

f fare a pair of standards bolted upon the respective side frames a a immediately behind the standards d (1 f f are a pair of arms pivoted by studs f f passing through their rear ends into the standards f f, respectively, from which they project, standing parallel with each other over the blanket cylinder 0 and at right angles with it. The front ends of the arms f carry a shaft f with its axis parallel with and in the same vertical plane as that of the shaft 0. This shaft f serves as the axis of a drum f, revolving freely thereon.

f are a pair of collars fast on the shaft f They serve to prevent the drum moving to either hand out of its proper position, which is over the printing-disks of'the numbering-machine. The function of the drum f is to carry the inking-band f, from which the types of the printing-disks take their ink as they and the band pass and touch each other. This band isacontinuous one. Neither the other drum or drums about which it is led nor the mechanism by which it is inked and traversed are illustrated, first,because the construction and action of such devices are well understood,and, secondly,because they do not form any part of the present invention.

f f are stops fast on the standardsf and engaging in slots f f in the armsf j", for the purpose of preventing them dropping low enough for the contact between the inkingband f and the types of the printing-disks to become too close.

1. .MechcZ-ntsm for rotating the printing- (Zish's continuousZy cmdfor making the emitsdish present a fresh type after each impressi0n.This consists of four gear-wheels g, h, t, and j, pitched and working together in a novel manner. The wheel g is the driver and is held concentrically on the shaft (Z by the following devices: g is a bush fast on the side of the wheel g, preferably by being integral with it. It and the wheel are bored to fit and revolve together about the smaller periphery of a sleeve 1", described farther on. This sleeve is held fast to the shaft (Z in the way described farther on and the wheel 9 to the sleeve by screws and to the shaft by the gib r. The wheel periphery of the collar g, and the shaft (Z are concentric with each other. The bore of the collar g shares the eccentricity of the sleeve r. h is the sec- 0nd and 't the third wheel. The former meshes with the driver g. The wheels h and t are held together in order that they shall both revolve with the same angular velocity, but provision must also be made for theirbeing adjusted circumferentially in respect of their several positions about their common axis. The device illustrated for holding them together and for providing for their adjustability also consists of a pair of set-screws h h, which pass through arc-shaped slots h h in the wheel h wide enough to pass their shanks,which are screwed into the wheel 1'. h is a shaft fixed parallel with the shaft (Z to the standards f f. It receives a loose bush h between a pair of collars h" h, which are made fast to it. The wheels h andi are mounted concentrically upon the bush h and are made fast to it by set-screws h'. h is a distance or packing disk between the said wheels.

j is the fourth wheel. It is bored out concentrically to fit upon and revolve about the bush g, already described, and therefore concentrically with the driver g. The ratios of the four wheels in respect of diameter are as follows: The driver and second wheel 9 and h are equal, but the third wheel 1' is one-tenth larger than the fourth wheelj. The distance between the axes of the shafts (Z and h is settled by the diameters of the wheels 9 and h.

The units-disk Z and the others of the series receive their motion from the wheelj, through a connection which is described farther on. If the ratios of the four wheels g, h, t, and j were such that the last of them-the wheelj would revolve with the same velocity as the wheel g the velocity of the units-printingdisk Z would be only that which the sleeve 0" and the wheel 9 have in common. This velocity, which for the purpose of this specification is hereinafter referred to as the normal one, would obviously lead to a repetition of the last impression.

According to the present invention we make special provision for giving the units-disk a velocity higher than its normal one. This acceleration suffices to substitute the next type for the one which has just made an impression upon the paper, the acceleration in question being effected during a rotation of the disk upon its seat. The amountof it is according to the system of notation for which the numbering-machine is made and is produced by the differentiation. in the diameters of the wheels j and i, the latter being the larger wheel. As the machine illustrated is made for the decimal notation, the respective diameters of the two wheels are as ten to eleven. Therefore while the sleeve 1' and the wheels g, h, and t are making one revolution the wheel j and the disk Z make one and onetenth.

The connection between the gear-wheel j and theunits-printing disk, Z is a self-adjusting one, and consists of a stud k on the former entering a slot Z in the latter. This connection isv self-adjusting in respect of the radial distance between the axis of rotation and the point at which actual contact between the said stud k on the one hand and the said disk Zon the other takes place, for that distance must vary from one moment to the other in the way and for the reason next described and explained.

h is a stud fast to the fourth wheelj and projecting from it in a line parallel with the axle of the shaft d. It engages with the unitsprinting disk Z by entering a radial slot Z cut in it for that purpose. The reason for there being a radial slot instead of a hole to receive the stud h is that the motion of the said disk is eccentric to, while that of the stud is concentric with, the shaft d. The position of the stud in the slot is therefore constantly changing. At one moment it is at the outer end of the slot, as illustrated in Fig. 4, and at another it is at the inner end. The rate at which the units-disk Z moves varies accordingly, and this variation must be compensated for by setting the type Z on it at varied distances accordingly, as they are shown to be in Fig. 8, because if they were set at equal distances they would not be brought up to the printingline punctually. They would be either too soonor too late. The gear-wheelj is thus adapted to travel at the same angular velocity which it is required shall be imparted to both the said wheel and the disk 1. The above-mentioned combination of radial slot Z in the disk Z and stud K, fast on the wheel 9' and projecting therefrom into the said slot, constitutes a self -adjusting connection between the twoself-adjusting, that is in respect of the constantly-changing position of the stud in the slot.

2. flfechanisni for preventing the impression being sZa'rre(Z.-lt is obvious that if the gears g, h, i, and j have all their teeth pitched alike the fourth wheel j, and consequently the printing-disks, will be rotated at a regular rate throughout their revolutions. Our invention provides for the rate of the printing-disks being varied to the extent of their receiving a slower movement from the commencement of the impression to the end of it. The advantage gained by the said slower movement is the obviation of the risk of the impression being slurred. According to this part of our invention, the wheels g and j, the driver and the fourth, and the greater portions of the peripheries of the intermediate wheels h and i are pitched alike; but the re maining portions of the two last-mentioned wheels are pitched differently and also differently from each other as follows: The wheel h has sixty-three teeth and a normal pitch of- Seven of its teeth h-those included between the pairs of arrows in Figs. 1 and 3 have a pitch of .3l %:.323, or one-twentieth less than the normal pitch. The wheel i has sixty-six teeth and anormal pitch of .34.-

pitch of .Si-i-- fizi'i, or one-twentieth greater than the normal. This differentiation in pitch can be perceived by comparing the distances between the radii through the normally pitched teeth and those drawn through the abnormally-pitched ones in Figs. 3 and 5. It is to be noted that the two sets of seven teeth coincide with each other set with set. This coincidence will be understood from a comparison of the representations of the wheels h and i in Figs. and 5, its object being to provide that the respective meshings of the teeth h with the driver g and of the teeth i with the fourth wheel j shall be synchronous with each other and with the impression.

\Ve do not confine ourselves to differentiating the pitch of only seven teeth in each of the intermediate wheels, but may differentiate the pitch of as many as the circumstances of any particular case may render necessary to secure the desiderated slower movement during impression term. The shaft h" is preferably held to the standards ff by a pair of set-screws i i The coned ends of these screws enter holes of a corresponding contour in the respective ends of the shaft h. These holes (not shown in the drawings) are eccentric to the shaft, the object of this eccentricity being to permit of the distance between the axes of the shafts (Z and It being adjusted at the time that the numbering-machine is being erected.

3. llfechanisrn for advancing the printingdishs to the paper before the impression is made and for withdrawing them from the paper aflerward.-l, in, n, 0, p, and q are a series of six printingdisks. Each is provided with radially-projecting type Z in n, &c., according to the decimal notation, the value of the disks rising accordingly in the direction of the disk q and the quantity of disks being decided by the highest number which the machine is required to print, as heretofore.

The improved mechanism for advancing and withdrawing the disks consists of a cylindrical surface eccentric to the axis about which it is rotated and upon the eccentric surface of which the printed disks are carried and rotated independently of and concentrically therewith. The eccentric surface in question is provided with the sleeve r. It is shown as made with three different diameters. The periphery r of the smallest diameter carries the units-disks Z and the before-described bush g of the driver g. The periphery r of the intermediate diameter carries the rest of the printing-disks, while the periphery r of the largest diameter provides an annular shoulder r against which the highest-value disk q bears. The three peripheries are concentric with each other. The sleeve r is bored longitudinally to fit on the shaft cl, but its bore on the one hand and the three peripheries 011 the other are eccentric to each other, the degree of eccentricity being equal to the desiderated advance or withdrawal of the disks to or from the paper. The said sleeve is fixed fast, but removably upon the shaft cl by a setscrew r which bears upon a gib r, lying in the slot r in the shaft (1.

4:. lllechanisrn for rnahing the tens and higher value disks present afresh type after each impression, Figs. 3 and 4E, and 6 to 10.- The units-printing diskl is bored out concentrically to fit upon and rotate freely about the periphery r of the sleeve r.

n is a radial spring-arm made fast to the outer face of the disk by a screw-pin i passed through the inner end of the arm into the disk. The arm lies normally within a radial groove Z cut in the said face to receive it. This groove is cut, preferably, just behind, with reference to the direction of the disks rotation one of the type Z.

Z is a finger carriedbythe outer end of the spring-arm n This finger is as long as the disk Z is thick. (See Fig. 9.) Its function is to engage behind a type on the tensdisk nfor the purpose of rotating the latter one number forward e. g., from '7 to 8. The groove Z is deepened toward the edge of the disk to allow of the engaging motion of the said arm and finger. The arm a and finger Z are actuated by the following device, (see Figs. 4 and 15 is an annular concentric groove cut in that face of the driver 9 which is next to the fourth wheel j. g is a cam-s urface held there in and to the driver by screws g. The effective arcual length of this cam-surface is the circumference of the groove g divided by the number of types on a printing-disk.

7c is a push-piece standing parallel with the axis of the shaft (Z and capable of working to and fro through a hole in the fourth wheel k is a springmade fast byscrews 7c passed through its base into the said wheel j.

t is the operative nose of the spring and stands away from the wheel 7' in the groove g This is best seen in Figs. 6 and 7. It is connected to the adjacent end of the pushpiece 70 by entering a small hole 7c therein. (See Fig. 4.) The spring k normally holds the push-piece 7c in the position illustrated in Fig. 4- 5. 6., with its nose just clear of the opposite face of the units-disk Z. The rise of the cam g is parallel with the axis of the shaft (Z and is equivalent to nearly the thickness of the printing-disk Z, the object of such equivalence being that the engagement of the push-piece 7a with the said cam-surface g shall protrude the said push-piece far enough in a line parallel with the axis of the shaft (Z to insure its making the finger Z stand across the periphery of the tens-disk on between two of the type m.

70 is an arcual enlargement of the groove Z*. The object of this enlargement is to make room in the printing-disk Z for the nose of the push-piece 76 to move parallel with the axis of the shaft (Z as well as about it as a center during the time that it is pushing the spring-arm "L02 far enough and keeping it there long enough to make the tens-'diskm present a fresh type m in the printing-line.

The change of type in the printing-disks of higher value than the tens-disk is effected by the following devices, (see Figs. 11 and 12 to 16:) Each disk from the tens-disk m up to the one of highest value but one engages just before the end of its first revolution with the one of higher value by means of the following device with which each of the said disks is fitted.

s is a slot cut in the disk near to its periphery and parallel with a diameter of it.

s is a catch standing normally within the slot .9. It is pivoted to the disk by a pin .9 which passes through it transversely and midway of its length. The leading end of the catch 8 is inclined away from the adjacent disk with which it is to engage in the direction of the nose .9 of the catch. The edge of the nose is radial to the disk and the sides of the catch are at right angles with the said edge. The catch is kept in its normal positioni. c. within its slot sby two forces actin g on it from opposite sides of its pivot, viz.

on one side a radial bar-spring s, the base of which is recessed in the distance-ring and held to the disk by screw-pins s, and on the other side the contact of the adjacent face of the lower-value disk with the face of a stud .9 which projects from the catch beyond the face of the respective disk for a distance equal to the thickness of the distance-ring Each distance-ring is in one piece with its disk. Zach disk from the tens-disk m upward has ten sockets formed in one of its sides for the catch of the respectively lowervalue disk to engage in from time to time, as may be required to rotate it. These sockets are equidistant from each other and all in the path of their respective catches. They are illustrated as being radial. slots 5 cut through the respective disks. There is combined with each nine of the slots and entering them on their rear sides (see Fig. 13) a tangential incline 3 down which the nose of the engaging-catch can slide. The tenth incline is lost in the slot 8, except in the case of the highest-value disk q, because the latter has neither slot snor catch 5 in it, inasmuch as being the highestvalue disk in the series it has not to move any disk. The act of en gagement of a catch with thenext highervalue disk is illustrated in Fig. 16. No engagement 011 the part of any catch is possible until there are in position a socket to receive the nose of a catch and a cavity to receive the tail of the catch. These cavities are provided by the rear portions of the slots .9. As there are not any slots in the units-disk Z, there is formed in the side of the latter and between the types 1 and 0 an inclined notch Z. The depth of the notch increases in the direction of rotation, as shown by the dotted lines in Fig. 10.

The position of the notch Z with reference to that of the type on the disk Z, as well as with reference to that of the finger Z is important. The function of the said notch is to receive in its deepest part the tail of the catch 5, carried by the tens-disk on, whenever it becomes necessary for the said catch 5 to engage in one of the slots 3 in the disk or to make the latter present a fresh type 11. in the printing line. Therefore the notch Z occupies the respective dimensions and position illustrated in Fig. 82'. 8., between the O and 1 typesat the same radial distance from the axis of the shaft (Z as the tails of the catches s, with its deepest part behind the 1O type (speaking in terms of the direction of rotation) and its shallowest part merging into the side of the printing-disk along a radius in front of the 1 type. Further, seeing that the disk 71 is moved over the sleeve periphery r by an engagement between the catch 5 and a slot 5 just mentioned, and that the disk on can be moved over the said sleeve periphery only by the finger Z engaging behind one of its types on, the arcual distance at which the said finger is fixed from the deepest part of the notch Z must be so adjusted that the tail of the catch .9, carried by the disk m, will swing threinto at the moment when the said finger l engages behind one of the type m.

The highest-value disk q does not require a catch, but only slots .9 and inclines 8" thereto. Each of the printing-disks of higher value than the unit-disk Z hasten equidistant notches if out in the face of the bore of it and transversely of said face. Each notch is radially coincident with the center of a printin g-type.

t t are radial holes bored into the sleeve '7' in the respective planes of the last-mentioned group of disks These holes are set out in ten equidistant rows parallel with the axis of the sleeve.

t are locking-catches, each capable of sliding into its cavity flush with the periphery r of the sleeve.

i f are the catch-protruding springs.

The nose of each catch is chisel-shaped to fit into the notches tof its respective disk.

The machine, constructed as above described, works as follows: Let it be supposed that all the printing-disks present their 0 types in the printing-line. The unitsdisk l is held in that position by the engagement of the stud 7,: in the radial slot Z and the highervalue disks by the engagement of their locking-catches I? in the respective notches t. The radius of the maximum eccentricity of the sleeve 9' is aligned with the vertical diameter of the cylinder 0. The two sets of teeth that are pitched out of the normal in the wheels i and j mesh together. The pushpiece k stands with one end in the groove g in front (speaking with reference to the direction of rotation) of the step or drop of the cam-surface g and the catches s in the position indicated by the dotted lines in Fig. 1oi. 6., with their noses 5 each in a slot 5 The sleeve 7' revolves about its own axis once for each impression, during which revolution the types are inked as they pass the inking device. As the rate at which the sleeve r revolves is regular, that of as many of the printing-disks as are free of the direct control of the wheel. j is regular too, forthey are carried by it, being held to it by the lockingcatches '6 Printing 1mits.The wheel j makes one and one-tenth revolution for each one that the sleeve '7 makes and in the same time. Further, it always has the units-printing disk Zfast to it. The consequence is that the end of the first revolution of the sleeve finds the 1 type on the said disk Z brought into the printing-line and the impression is 000001 instead of 000000. The accelerated speed of the units-disk Z is constant, so that at the end of the second revolution it has gained twotenths of a revolution upon the sleeve periphery 2', whereby the 2 type of the series I is brought into the printing-line, and so on in regular sequence so long as the machine is at work.

Printin g tens.-The printingdisk m is brought into and maintained in operation as follows: By the time that the highest unitary impression 000009 is made the disk Z has gained nine-tenths of a revolution upon the sleeve 1*. During that revolution of the sleeve periphery 0, which immediately precedes the next impression 000010, which latter is the initial of the next higher class of values after the units, there will take place the first of the engagements between the push-piece 7t and the cam-surface g. The object of such an engagement is to move the tens-disk on through one-tenth of a revolution in addition to that which it receives from the sleeve periphery. so that the said disk on may present a fresh type in the printing-line at the end of each tenth revolution of the units-disk Z. Each engagement projects the finger Z across the periphery of the tensdisk m, making it stand behind one of the type m thereon. The continued rotation of the disk Z takes the finger Z up to the said type, and therefore the disk on along with it. The engagement lasts for one-tenth of a revolution of the sleeve periphery r and is an acceleration of the normal rate of the said sleeve periphery r to the same extent. As the type m are thirty-six degrees apart from each other, such acceleration presents the 1 type of the series m in the printing-line by the side of the 0 type of the series 1 on the disk 1, which last-mentioned type has been brought there by the contemporaneous revolution of the said disk. The disk at is held in its new position by the engagement of the respective lockin g-catch t in a fresh notch 25 in it. The next impression is therefore 000010.

It has already been explained what are the necessary dimensions of the cam-surface g in respect of its length and of its projection or rise from the bottom of the groove 9 Its position in the latter is of equal importance, and will be understood from the following detailed description of the engagement between the pushpiece k and the said cam-surface g. This engagement takes place and may take place only during that revolution of the sleeve 0' which follows any impression the unitary value of which is nine. It is brought about as follows: The push-piece k rotating at arate one-tenth faster than that of the cam-surface g, comes up with the latter where the bottom surface of the groove 9 merges into the said cam-surface immediately after the impression last referred to, and travels over the said camsurface g during the following revolution of the sleeve periphery r during which revolution the finger Z on the spring-arm a (the latter being actuated by the push-piece k is projected across the periphery of the disk m and engages with the type m in front of it. When the revolution in question is finished, the push-piece k leaves the cam-surface g and is withdrawn from the spring-arm n by the spring k The above-described co-operation between the cam-surface g, the push -piece 713 the spring-arm M the finger Z and one of the type m is repeated during each subsequent tenth revolution of the sleeve periphery 7 whereby the tens-disk 'm is made to present in the printing-line all its types, one after the other, in the order of their value. The recurrence of the same type m in each of the nine revolutions of the sleeve periphery which intervene between any two of the tenth revolutions mentioned in the preceding paragraph, is due to the engagement of the respective locking-catch i in the proper notch t in the disk m, whereby the latter is held to the sleeve periphery 0- and must rotate with it. 'During the said intervening nine revolutions the notch Z will move over the tail end of the catch carried by the printing-disk m nine times, but at none of these contacts will there be an engagement between the said catch 5 and the printing-disk n sufficient to move the latter, because the slot Z moves smoothly over the tail end and the said disk '11 is held to the sleeve periphery r by its locking-catch The engagements of the finger Z behind the types m always take place at the same point in the revolution in the machine, and consequently each engagement is with the type 012 that stood behind the one concerned in the immediately preceding engagement.

Printing 7mvzdreds.'lhe hundreds-printing disk n is brought into and maintained in operation as follows: At the moment when the nine types on the printing-disks Z and m are side by side in the printing-line the deepest part of the notch l in the said disk Z is opposite the tail end of the catch 5, carried by the disk m, and the nose 3 thereof opposite the radial slot 5 close to the 1 type of the or series. The respective spring 8 swings the said tail end into the notch l and the said nose 8 into the said radial slot 3 This engagement of catch 3 and slot 5 is accompanied by that of the finger Z behind a type on. This double engagement puts both disks m and at under the control of the stud 70, fast on the wheelj. Consequently, during the revo lution of all the parts mentioned, which follows the impression 000099, the disk Z brings up its type 0 into the printing-line, moves the disk in through one-tenth of a revolution beyond that shared by it with the sleeve periphery T the latter brings up its type 0 into the printing-line and further liberating the disk or from the hold of its locking-catch 79 makes it partake its own accelerated motion of one-tenth of a revolution and bring up its t 1 into the printing line also, whereupon the disk at is re-engaged by its locking-catch 2?. The next impression will be 000100, which is the initial impression of the next higher class of values after the tens. The cycle of changes from 1 to 99, or the part of the disks land m will be repeated, during which repetitions the disk it remains locked to the sleeve periphery 0' Then the engagement above described between the deepest part of the notch Z and the catch 8', carried by the disk m and a radial slot 5 in the disk 02 is repeated, only this time it is the slot 8 next to the 2 type of the n series which is concerned instead of the one next the 1type. lVhcn the impression 000099 has been made, the catch 3 in the disk at engages during the revolution of the sleeve 0 immediately following such impression in a radial slot 8 in the disk 0 and moves it through one-tenth of a revolution in addition to that which it shares with the said sleeve.

All subsequent changes of type on any printing-disk are effected in the respective ways described above.

It should be borne in mind that all the printing-disks from and including the tens disk an upward are held in their respective positions upon the sleeve periphery r by the respective locking-catches t and that one of such disks is liberated from the hold of its catch 15 only by the engagement of the finger Z behind the type m at the moment of and by which engagement the driving energy of the stud 7c is brought to bear upon through the intervening parts, upon the hold of said lockin gcatch i upon the said disk.
